Interview was very casual. Got offered an interview after dropping off a resume in person. Had to reschedule the interview due to an exam, but I ended up finishing the exam early and phoned to ask if it was possible to come in that day for an interview. Manager was pleasantly surprised, and said sure. I came in, did the interview, which mostly consisted of him describing the job and asking about certain aspects of said job, could I do them, etc. He asked if I had any questions and I said no. A day or so later I got a call saying I got the job.
